Caller ID Decoder
(Complete Item Description)
- Abstract:
The telephone company's "Caller ID" service provides the calling party's directory information as well as the time and date of the call as an FSK (frequency shift keying) signal between the first and second rings of a telephone call. In this project, develop a complete Caller ID decoder that analyzes an audio recording of the FSK signal to extract the directory and date information for display.
